Maybe they started referring to this as a category once West World hit it big? Anyway there is also Wynonna Earp. (From imdb - "Following Wyatt Earp's great great-granddaughter as she battles demons and other creatures. With her unique abilities and a posse of dysfunctional allies, she's the only thing that can bring the paranormal to justice. ")PML as The Mandalorian listed as a Space Western instead of a Science Fiction. Is that a category now after Firefly? As much as I enjoy The Mandalorian, Firefly still wins as best Space Western of all time.
